Web Intelligence client eating CPU.

HI,

I'm responsible of a farm of Windows Remote Desktop Servers (Virtualized).

User are working through RDP sessions.

I'm facing a problem where Web Intelligence (Platform 4.1 Support Pack 2) accessed through Firefox or IE is eating my CPUs.

After a while (several minutes) being idle, the user just checking his request results or doing something else with another software, the browser left as is, it starts to eat the cpu (10% of a 10 cores, 20% of a 5 cores). Tested on different servers.

Any hints on that ?

    Hi,

    I'm not sure the process or workflow is relevant. This is a client-side problem (Firefox, IE), after the query is completed, not a server-side problem.

    I'm by no mean a BO manager/specialist. I'm Windows sysadmin seeing CPU eaten by either Firefox or IE displaying a Web Intelligence query result. Looks like some javascript is going crazy after a while.

    See capture. I've run a small query, left the browser alone for a while and now it take 15% of the CPU.
